This calculates an AES MAC over the 0x20-byte buf1 SHA-256 hash. When this MAC matches the MAC stored in buf0, result-code 0 is returned, otherwise an error is returned. This is used to verify the DSiWare section's [[DSiWare_Exports|metadata]] MAC after decrypting the payload data. | This calculates an AES MAC over the 0x20-byte buf1 SHA-256 hash.
